Here, I’ve mentioned a few top practices that you should consider to protect your Plesk dedicated server. So, let’s examine them!

1. Timely Up-to-Date Plesk:

Before proceeding, ensure that your Plesk configurations are up to date. Plesk updates automatically install any components required to significantly improve server security. Therefore, the best way to secure a Plesk server is to keep it up to date. Use the following methods to determine whether you have an updated version:

On the options menu, choose “Automatically install Plesk updates.”

As part of the security updates, you should double-check the installation of Plesk Firewalls, Fail2Ban, and ModSecurity.

2. Security Procedure:

Safe FTP connections to the server can be possible depending on the Plesk security settings. Besides, by inputting a strong password, you can modify the password settings.

To alter the minimal password necessary:

Select your preferred password policy strength by navigating to the “Security” tab in settings, then to the “Password Strength” tab. Push the OK button now.

If FTP only permits authorized connections to the server, attacks can be avoided. Therefore, increase the security of Plesk by securing the server with a strong password that thwarts attempts to hack the main login. By using this method, we are preventing server-side brute-force attacks.

3. Attack Utilizing Force and Fail2Ban:

The log files on the Plesk server are kept track of and protected from brute force assaults with the aid of Fail2Ban. Any unlawful login is viewed suspiciously by it. Consequently, the Fail2Ban notifies the user or temporarily blocks their IP address from accessing the server if any of these login attempts are made.
